If x is the probability of an event happening, then which of the following represents x?
1 answer:
Answer: The correct option is (C)
Step-by-step explanation: Given that 'x' is the probability of an event happening.
We are to select the correct statement that represents 'x'.
We know that the probability of the happening of an event is always lie between 0 and 1.
If the probability of an event is 0, then it is a null event.
If the probability of an event is 1, then it is a sure event.
The probability of all other events lie between 0 and 1.
Therefore, the statement that represents 'x' is
Thus, (C) is the correct option.

The volume and surface area of the pyramid will be 392 / 3 cubic units and 189 square units. Then the correct option is A.
The complete question is attached below.
<h3>What is the volume and surface area of the pyramid? </h3>Suppose the base of the pyramid has length = L units, width = W units, slant height = K units, and the height of the pyramid is of H units.
Then the volume of the pyramid will be
V = (L × B × H) / 3
The surface area of the pyramid will be
SA = 2(1/2 × B × K) + 2(1/2 × L × K) + (L × B)
Then the volume will be
V = (7 × 7 × 8) / 3
V = 392/3 cubic units
Then the surface area will be
SA = 2(1/2 × 7 × 10) + 2(1/2 × 7 × 10) + (7 × 7)
SA = 189 square units
Then the correct option is A.
